update to 1.17

[Fourmisain]

The process looked like this:

• run gradlew migrateMappings --mappings "1.17+build.10"
  • update to gradle 7.0.2, remove deprecated jcenter()
• update to loom 0.8, Java 16 (now required for building)
• update dependencies
• mixin into new renderTooltipFromComponents() taking List<TooltipComponent> instead of renderOrderedTooltip() taking List<? extends OrderedText> because the latter directly calls the former

Note: This could have unintended side-effects I'm not aware of.

• fix drawTooltipIcons(): RenderSystem.scalef() doesn't exist anymore, replaced by matrices.scale(). RenderSystem.enableRescaleNormal() seems to have no replacement at all, so I just left it out - let's hope this is fine.

• fix drawScaledItem():

Here, matrices.scale() doesn't work because renderGuiItemIcon() uses a different MatrixStack, namely RenderSystem.getModelViewStack(). It also calls RenderSystem.applyModelViewMatrix(); after it changing it - I have no idea what the latter does, but I applied it anyways.

I didn't do a ton of testing but so far everything seems fine. You might wanna pull this and push it to a separate branch because GitHub doesn't allow PRs to new branches

Thanks for the pr, I'll do the basic testing I usually do when I make big changes and I'll just release it as a beta for now just in case something is in fact broken.
